Austrian company SML and partner KIEFEL in a joint project to develop foamed sheets for hot-fill applications with new features in terms of heat resistance, thermal insulation and recyclabili.
Single-material expanded PET or PP sheets produced by SML's new system are expected to replace hot-fill applications made from expanded polystyrene, which are often difficult to recyc.

The foamed sheet produced by SML's new production line has an A/B/A sandwich structure, in which the middle sandwich B layer is a foamed material, and the two outer layers are a hard materi.
Compared to PET sheet with the same properties, the single-material structure facilitates recycling, while the foam layer enables 50% weight reducti.

In a new collaborative project, Kiefel and SML are further developing the application potential of this foamed she.
The initial results of the research were optimistic: the cups produced were heat-resistant up to 100 degrees Celsi.

Unlike polystyrene, single-material foamed board, especially PET foamed board, can be recycled directly because there are mature recycling facilities and technologies in this ar.
Hot fill applications made from foamed PET sheet can be easily processed with other single-use PET produc.
